Improvement in sheet-metal packages



UNITED STATES PATENT OEEIoE;

JOHN F. ROSS, OF TORONTO, ONTARIO, CANADA, ASSIGNOR OFY ONE-HALF HIS RIGHT TO WILLIAM FRANKLIN ROSS, OF SAME PLACE.

IMPROVEMENT IN SHEET-METAL PACKAGES.

Specification forming part of Letters Patent No. 209,987, dated November 19, 1878,' application filed June 13, 1878.

To all whom it may concern:

Beit known that I, J oEN FoRsTEE Ross, of the city of Toronto, in the eountyof York, in the Province of Ontario, Oanada, have invented certain new and useful Improvements in Sheet-Metal Packages, of which the following is a specification:

My invention has relation, first, to improvements in the manner of fasten in g and securin g the heads of cylindrical sheet-metal packages for white lead, paints, oils, lard, and other materials.

My invention further relates to a novel ar rangement of the handle or bail of said package, by which it may be carried, and utilized for various purposes when empty, and which is so arranged, 1n connection with pivoted lugs, that it may be folded out of the way, to offer 11o obstruction when a number of packages are packed together during transportation from place to place.

In the accompanying drawings, Figures 1 and '2 are perspective views of a package, in the construction ot' which my improvements are embodied. Figs. 3, 4, 5, and 6 are details, showing construction.

A is the body of package, which may be constructed of any of the descriptions of sheetmetal plate usually employed'for this purpose. The bottom and top edges are folded over to form a shouldered recess or crease, extending around the whole diameter ot' cylinder, as indicated by letter B. Into this recess a correspondingly-turned edge, O, on the dished heads Dis arranged toiit. To allow of the insertion of the edge O within the recess B one or more slits, b, are made in the upper overlapping edge of the cylinder and in the edge of the head, as at c. The metal on one side of these slits is depressed and the opposite side is raised,

thus forming a tapering entrance into the recess of ascrew-thread nature, which permits the edgeef the head to be screwed into the recess B, by bringing the slits of the head and cylinder together, and turning the former around until the whole of the edge C passes into the recess B. The heads may then be secured in place by pressing or rolling down a portion or the whole of the overlapping edge ot' cylinder. For obvious reasons the head forming the bottom of the package should be secured as permanently and tightly as possible, by rolling or otherwise; but the head rbefore it would be fully secured. By making two oppositely-placed slits in both head and cylinder but half a revolution would be necessary.

the heads are, that packages can readily-be closed and opened with little labor and without damage. A further advantage is, that the construction is cheap and strong.

F is a bail, secured to the ends ofthe pivoted lugs or ears E, to form a double joint,A

which,` while it will allow the bail to be extended and used as an ordinary bail, will fold together, the lug inclining in one direction and the bail-wire in the opposite direction, and

bind tightly within a groove, a, sunk in the cylinder. The bail is not intended to be used for carrying the package when packed, (for this purposea handle, G, is riveted on the cover.) but to enable the package to be utilized, when empty, as a pain t-pot or other useful service. v

It is evident that an equivalent connection between the head and cylinder could be made by overlapping the edge of the head on a straight outwardly-extended edge of the package. This construction merely reverses the position of the parts, without altering the spirit ot' the invention, and is therefore a mere equivalent.

I claim as my inventionl.V The head D, provided with the slitted differentially-inclined edge O, in combination with the cylinder A, provided with the 'recess B, and having the upper lapping edge slitted and deiiected to correspond with the head arranged and operating substantial] y as shown and described.

2. The bail F and pivoted lugs E E, in combination with the cylindrical package A, provided with the groove a, substantially as shown and described.
